macio: Delete unused "macio-gpio" devices

Browse Source 
These devices go with the "via-pmu" device, which is controlled by
property "has-pmu".  macio_newworld_init() creates it unconditionally,
because the property has not been set then.  macio_newworld_realize()
realizes it only when the property is true.  Works, although it can
leave an unrealized device hanging around in the QOM composition tree.
Affects machine mac99 with via=cuda (default).

Delete the unused device by making macio_newworld_realize() unparent
it.  Visible in "info qom-tree":

     /machine (mac99-machine)
       [...]
       /unattached (container)
         /device[9] (macio-newworld)
           [...]
           /escc-legacy-port[8] (qemu:memory-region)
           /escc-legacy-port[9] (qemu:memory-region)
           /escc-legacy[0] (qemu:memory-region)
    -      /gpio (macio-gpio)
    -        /gpio[0] (qemu:memory-region)
           /ide[0] (macio-ide)
             /ide.0 (IDE)
             /pmac-ide[0] (qemu:memory-region)
